Article Summary

Christoph Thetard has developed a mechanical flywheel drive to power a set of kitchen appliances for his Diploma in Product Design at Bauhaus University in Weimar, Germany. The kitchen machine, coffee grinder and hand blender chosen for this device would under normal circumstances need to be plugged into an electrical wall socket, but there's no electricity needed for R2B2. Pumping the pedal spins the flywheel, which in turn provides the energy needed to operate the three cooking aids.
